1. Quick Start shall enable the chiller to restart in 15 seconds the power is restored.<br />

Quick Start minimizes the time to restart <strong>and</strong> loads the chiller as quickly as<br />

possible, to rapidly achieve the leaving chiller water temperature setpoint. The<br />

main objective is to provide minimum down time <strong>and</strong> the fastest restart/loading<br />

as possible. Once the chiller is running <strong>and</strong> close to setpoint, it will return to<br />

st<strong>and</strong>ard chiller YK control<br />

2.7 SOURCE QUALITY CONTROL<br />

A. Perform functional tests of chillers before shipping.<br />

B. Factory performance test chillers, before shipping, according to ARI 550/590.<br />

1. Test the following conditions:<br />

a. <strong>Design</strong> conditions indicated.<br />

b. Reduction in capacity from design to minimum load in steps of 10 with<br />

condenser fluid at design conditions.<br />

2. Prepare test report indicating test procedures, instrumentation, test conditions,<br />

<strong>and</strong> results. Submit copy of results within one week of test date.<br />

C. For chillers using R-134a refrigerant, factory test <strong>and</strong> inspect evaporator <strong>and</strong> condenser<br />

according to ASME Boiler <strong>and</strong> Pressure Vessel Code: Section VIII, Division 1.<br />
